12v Motors are kind of everywhere. An old printer would have some. You might look at an old scanner. The motor out of an air mattress inflator. Even bathroom fans use 12v motors. They convert from 110 - 12v. My office looks like Sanford & Sons! LOL! I never throw away an electronic. I salvage the parts out of everything. I even pull the IR LEDs out of remote controls before I throw them away. You should consider hording. It's a fun, rewarding hobby. LOL!
